Title: Momentum Management Algorithm for Pyramid Type Reaction Wheel on Geostationary Satellite
Inventor: PARK YEONG UNG
IPC: B64G1/10
Filed: 2002-09-27
Abstract: PURPOSE: Pyramid-type reaction wheel momentum management algorithm of a geostationary orbit artificial satellite is provided to automatically manage the reaction wheel algorithm by separately discriminating the momentum management algorithm at a dumping mode and a station keeping mode. CONSTITUTION: Pyramid-type reaction wheel momentum(W1,W2,W3,W4) management algorithm of a geostationary orbit artificial satellite automatically manages steps of deciding dumping execution by separating a stable region and a normal operation range for the current reaction wheel momentum, separately considering a thruster set for four reaction wheels, and then deciding a thruster set adequate to produce torque in 3-axis directions. At a station keeping mode, the pyramid-type reaction wheel momentum management algorithm of the geostationary orbit artificial satellite calculates a torque value to be controlled for disturbance, decides the dumping state when the reaction wheel momentum is not in the stable region, and executes attitude control, using reaction wheels when the torque direction to be controlled and the torque direction to be dumped are not coincided.

Title: Method for processing outgoing call using terminating Basic Call State Model
Inventor: KIM DONG UK
IPC: H04M3/54
Filed: 2002-09-27
Abstract: PURPOSE: An outgoing trunk call processing method using a destination BCSM(Basic Call State Model) is provided to trigger a route to a service control point at a point when a route is occupied by using a recommended BCSM and route a call processing of a destination number or an originating number to a specific interval by a designated value. CONSTITUTION: When a call originating is made by a user(S100), an originating number is translated and processed so as to be connected to a corresponding routing(S200). After the originating number and a destination number are translated and routed, when an outgoing trunk occupation request is received, an outgoing trunk controller executes an outgoing process(S300). It is checked whether a destination BCSM has been registered in an outgoing route which has been required for a current call occupation(S400). If no destination BCSM has been registered, it is an intelligent network call and connected to an SCP(Service Control Point)(S410). After a service operation for a number change with respect to the originating number and the destination number is performed in the SCP(S420), the changed information is transmitted to a remote station and a call processing is performed(S600). If an event occurs during the call processing(S700), event information is transmitted to the SCP(S410).
